Answer:
Haley needs to print 65% of the tickets.
Step-by-step explanation:
Given that:
Tickets printed by Haley = 112
Tickets needed to print = 320
Tickets left to print = 320-112 = 208
Percent of tickets left to print = 
Percent of tickets left to print = 
Percent of tickets left to print = 0.65*100
Percent of tickets left to print = 65%
Hence,
Haley needs to print 65% of the tickets.
The expression factorized completely is (h +2k)[(h+2k) + (2k-h)]
From the question,
We are to factorize the expression (h+2k)²+4k²-h² completely
The expression can be factorized as shown below
(h+2k)²+4k²-h² becomes
(h+2k)² + 2²k²-h²
(h+2k)² + (2k)²-h²
Using difference of two squares
The expression (2k)²-h² = (2k+h)(2k-h)
Then,
(h+2k)² + (2k)²-h² becomes
(h+2k)² + (2k +h)(2k-h)
This can be written as
(h+2k)² + (h +2k)(2k-h)
Now,
Factorizing, we get
(h +2k)[(h+2k) + (2k-h)]
Hence, the expression factorized completely is (h +2k)[(h+2k) + (2k-h)]

Answer:
Step-by-step explanation:
first multiply 4 X 2= 8
8+2x=42
Now you are going to pass 8 to the other side by adding -
2x=42-8
2x=34
Now you are going to divide 34 between 2 to eliminate the 2 multiplying in the other side. 34 between 2= 17
X=17
